If we move in the direction of making a potion-able Life spell, I like the idea of it having higher requirements than normal. Plus, makes it a special thing that artisans can do (since I imagine most PCs don't have 20+ ranks in a craftsman)!
If you make it Artisan-only, that would be really weird, because our system has never promoted Artisans over any other crafter in terms of individual crafting skill (just the best discounts for all craft skills).
I don’t care if Life potions are weirdly more expensive than other spells, but making them have incredibly difficult requirements is pretty much the opposite of what I’m trying to accomplish.
Not every chapter has an active Artisan, much less enough to base a valuable resource on. If you want to require 50 PP, sure, okay.
Also, adding a necromantic alternative that results in execution is not going to result in saving the lives of new characters. It will result in their characters being ostracized and potentially unplayable.
